Glowing approach could aid carpal tunnel-related surgery

Fluorescein angiography capable of assessing neural blood flow in chronic nerve compression neuropathy

Glowing approach could aid carpal tunnel-related surgery

In modern office life, avoiding the onset of carpal tunnel syndrome might be a daily struggle. The worst case could mean needing surgery to alleviate compression of the nerves or to repair damaged nerves. Helping surgeons visually check the areas where neural blood flow has decreased due to chronic nerve compression can lead to improvements in diagnostic accuracy, severity assessments, and outcome predictions.

With this in mind, an Osaka Metropolitan University-led research team involving Graduate School of Medicine student Kosuke Saito and Associate Professor Mitsuhiro Okada investigated the use of fluorescein angiography, a method employed in neurosurgery and ophthalmology to highlight blood vessels, to visualize neural blood flow in chronic nerve compression neuropathies like carpal tunnel syndrome.

The team found that fluorescein angiography could detect a decrease in neural blood flow in rats and rabbits with chronic nerve compression neuropathy. The results also correlated with electrodiagnostic findings.

Then fluorescein angiography was used for human patients undergoing open carpal tunnel release surgery, and the data also correlated strongly with electrodiagnostic testing. The findings indicate that fluorescein angiography might possess high diagnostic capabilities to assess neural blood flow during surgery.

“In surgery for severe chronic nerve compression neuropathy, the surgeon’s experience plays a big role in judging whether the surgical range is appropriate or whether additional treatment is necessary,” graduate student Saito noted. “This research has shown that fluorescein angiography can visualize impaired areas and assess the impairment severity, so we believe that it has the potential to contribute to improving accuracy for related surgeries.”

The findings were published in Neurology International.

The hidden costs of free apps – more than personal data
2024-10-10
Procrastination, sleep deprivation and reduced focus are part of the price we pay for free mobile apps. This is according to researchers at Linköping University and RISE, who have investigated the costs hidden behind the free apps. Based on their results, they also have some advice for decision-makers.   Most of us are becoming aware that our digital attention is hard currency for companies like Google and Facebook. By analysing our digital behaviour patterns, they can target tailored advertising directly to our feeds. Our attention becomes the product that is sold to advertisers.

Hot dragonfly summer: species with darker wings have evolved to withstand heat and attract partners

Hot dragonfly summer: species with darker wings have evolved to withstand heat and attract partners
2024-10-10
Temperature determines where species can live and if they are threatened by a warming climate. So, for a long time, biologists studied how heat tolerance affects survival. Yet, less is known about how thermal traits influence reproduction, which is directly linked to extinction risk. Now, researchers in the US have examined if males of dragonfly species that produce sexual signals in the form of dark coloration on their wings are more resistant to heat. They published their results in Frontiers in Ethology. “We show that dragonfly species that have evolved dark breeding coloration on ...

Dr. Ho-Il Ji from the Hydrogen Energy Materials Research Center at the Korea Institute of Science and Technology (KIST, President Sang-Rok Oh), along with Professor Sihyuk Choi's team from Kumoh National Institute of Technology, announced that they have developed a new synthesis method that can significantly reduce the sintering temperature required for the densification process of the electrolyte in next-generation high-efficiency protonic ceramic cells. Existing solid oxide cells (SOC) can produce electricity in fuel cell operation and hydrogen in ...

Rage clicks: Study shows how political outrage fuels social media engagement

2024-10-10
A new Tulane University study explains why politically charged content gets more engagement from those who disagree. Researchers found a “confrontation effect,” where people are more likely to interact with content that challenges their views than those that align with them. The study analyzed data from Twitter, Facebook, and online experiments over time, including during the 2020 U.S. presidential election, and found that users frequently react to opposing viewpoints with heightened engagement, often ...

E-waste experts urge public: Stop trashing electronic products with ordinary garbage (International E-Waste Day)

E-waste experts urge public: Stop trashing electronic products with ordinary garbage (International E-Waste Day)
2024-10-10
To mark the upcoming International E-Waste Day, Oct. 14, consumers worldwide are urged to collect dead and/or unused electronics and electrical products and give them a second life through reuse or repair, or recycle them properly.   Above all: stop tossing them out in household waste bins. The Global E-waste Monitor 2024, authored by UNITAR in cooperation with ITU, reported almost a quarter of end-of-life electronic waste ends up in home trash, squandering billions of dollars worth of copper, gold and other precious metals, materials critical to the production of such products, along with valuable plastics, and glass. The 14 million tonnes of ...

Hospitals that are Understaffed for Infection Prevention and Control Have Higher Rates of Infection, Study Says Nearly 4 in 5 hospitals are not staffed at sufficient level to keep patients safe from preventable infections   Arlington, Va. — October 10, 2024 — Inadequate infection prevention and control staffing levels are associated with higher rates of healthcare-associated infections, according to a new study published today in the American Journal of Infection Control. The study, conducted by the APIC Center for Research, Practice & Innovation, summarizes a pilot project to evaluate a new online calculator aimed at providing facility-specific recommendations ...

Study reveals 85% of women prefer choice between self-sampling and traditional cervical screening

2024-10-10
A new study led by researchers at Queen Mary University of London reveals women would welcome the option to choose between self-sampling and traditional screening done by a nurse or doctor for human papillomavirus (HPV)-based cervical screening.  The study, published in the Journal of Medical Screening, assessed a group of 2,300 women aged 24-65 who had collected their own samples alongside having their standard cervical screening in 38 GP practices across England. Participants were asked about their screening preference and their attitudes toward being offered a choice between ...

Inspired by Spider-Man, a lab recreates web-slinging technology

Inspired by Spider-Man, a lab recreates web-slinging technology
2024-10-10
Every kid who has read a comic book or watched a Spider-Man movie has tried to imagine what it would be like to shoot a web from their wrist, fly over streets, and pin down villains. Researchers at Tufts University took those imaginary scenes seriously and created the first web-slinging technology in which a fluid material can shoot from a needle, immediately solidify as a string, and adhere to and lift objects. These sticky fibers, created at the Tufts University Silklab, come from silk moth cocoons, which are boiled in solution and broken down into their building block proteins called fibroin. ...
